INTRODUCTION
AD33 and AD35 are waterproof EC testers.
The housing has been completely sealed against
humidity.
All EC readings are automatically temperature
compensated, and temperature values can be
displayed in °C or °F units.
EC calibration is automatic at one point, while
temperature range is factory calibrated and can
only be adjusted by the user.
The AD33P probe supplied with the meters,
is interchangeable and can be easily replaced
by the user.
The encapsulated temperature sensor allows
fast and accurate temperature measurement
and compensation.
To prolong battery life, these models are pro-
vided with an auto-off feature that turns them
off after 5 minutes of non-use.
Moreover, when batteries become too weak to
ensure reliable readings the meter automatically
turns off.
Each meter is supplied complete with:
AD33P EC probe
4 x 1.5V batteries, button type
